Answer: 4.5 * 10^4
Step-by-step explanation:
Answer:
The period, in seconds to two decimal places is, 2.84 sec
Step-by-step explanation:
Using formula:
......[1]
where
T represents the Time period in second
l represents the length of the pendulum/
As per the statement:
Use the gravitational constant g = 9.8 m/s^2 , length of the simple pendulum(l) = 2 meters and 
Substitute the given values we have;

⇒
Therefore, the period, in seconds to two decimal places is, 2.84 sec
Answer:
13 ft.
Step-by-step explanation:
Lateral Surface area of a cube is the area of 4 sides, front side, back side, left side face and right side face.
It can be seen seen from the attached figure as well.
Each face in a cube is a square. And each side in the cube is equal.
So, Lateral surface area is nothing but 4
area of a square.
And we know that area of a square =
.
Hence, Lateral surface area = 
As per question:
= 676

Hence, side length of cube = 13 feet.
Tbh I don’t know and I hope someone gives you the answer
